• Axial Flexibility: The high elasticity of the rubber bellow compensates for the significant shaft runout and deflection often experienced by submersible pumps during "snoring" (running dry) operation.
• Dual Seal capability: Can be used as the lower seal (process side) or upper seal (oil chamber side) depending on material configuration.
Key Features
• Submersible Workhorse: A direct aftermarket replacement for the classic Flygt "Plug-in" rubber bellow seals used in 2000 and 3000 series submersible wastewater pumps.
• Debris Shedding Profile: The smooth, flexible rubber bellow design naturally sheds rags, fibers, and solids, preventing them from wrapping around the seal (ragging).
• Positive Friction Drive: The rubber bellow grips the shaft or sleeve to drive the rotary face, eliminating the need for drive pins that can corrode or shear in heavy sludge.
Workshop
This workshop is equipped with professional processing equipment and integrated with standardized material warehousing management, enabling a one-stop production process from precision machining to finished product delivery. It ensures part machining accuracy and production efficiency, meeting various high-specification manufacturing requirements.
Product Research, Development and Testing
Our Product R&D and Testing focuses on optimizing seal performance through advanced simulation and material analysis. All seals undergo rigorous trials, including thermal cycling and pressure tests, to ensure durability, minimal leakage, and long service life in demanding industrial environments.
Industry Solutions
Case Study
Municipal Lift Station: A sewage lift station faced frequent clogs. We replaced the seals with these Rubber Bellows Seals. The smooth rubber profile prevented hair and wipes from accumulating, keeping the seal faces clean and functional.
Testimonials
A reliable fix for our older Flygt fleet. The rubber quality is excellent and doesn't swell in our industrial waste mix.

FAQs about Metal Bellows Seals for High Temperature Pumps
Q: Is glue required for installation?
A: No, these are interference-fit seals. They are pressed into the seal chamber using a lubricant (oil/water). Glue can damage the rubber and cause misalignment.
